Rage Against The Machine

Rage Against the Machine isn't really the only metal band that matters, but their aggressive social and political activism is refreshing, especially in an age of blind (or usually self-directed) rage due to groups like Limp Bizkit, Bush, or Nine Inch Nails. Recorded in less than a month, The Battle of Los Angeles is the most focused album of the band's career, exploding from the gate and rarely letting go the whole way through.
